随着北京市经济的发展,服务业产出占GDP的比例不断增加,其碳排放量也逐渐增长。因此,服务业成为北京市节能减排亟需开拓的新领域,受到越来越多的重视。本文首先对北京市2005-2012年服务业直接CO2排放量进行核算,然后运用投入产出模型对服务业间接CO2排放量进行核算,最后对服务业直接和间接CO2排放量的增长原因进行分解分析。得出以下结论:北京市服务业间接CO2排放量远远大于直接排放量,前者是后者的6倍多;直接以及间接CO2排放量都呈增长趋势,并且间接的增长速度要快于直接;直接CO2排放量增长的主要原因是产业规模增大和直接CO2排放强度变化,虽然产业结构和直接能源消费结构变化起到了抑制作用,但影响较小。间接CO2排放量增长的主要原因是产业规模增大、产业结构以及间接CO2排放强度变化,间接能源消费结构变化起到了抑制作用,但影响也较小。
With the economic development in Beijing, the ratio of service output to GDP has been on the increase, and its carbon emissions have also been gradually increasing. Therefore, the service industry has become an urgent need to open up a new area for Beijing’s energy-saving emission reduction and is receiving more and more attention. This paper first calculates the direct CO2 emissions of service industry in Beijing from 2005 to 2012, and then uses the input-output model to calculate the indirect CO 2 emissions of the service industry. Finally, the reasons for the increase of direct and indirect CO2 emissions from service industries are analyzed . The conclusion is that the indirect CO2 emissions of service industry in Beijing are much larger than the direct emissions, the former is more than 6 times of that of the latter; the direct and indirect CO2 emissions are in an increasing trend, and the indirect growth rate is faster than direct; The main reason for the increase of direct CO2 emissions is the increase of industrial scale and the change of direct CO2 emission intensity. Although the change of industrial structure and direct energy consumption structure has played a restraint role, it has less impact. The main reason for the increase of indirect CO2 emissions is the increase of industrial scale, the change of industrial structure and the intensity of indirect CO2 emissions, and the change of indirect energy consumption structure, but the impact is also small.
